They look cool!
It’s a center lock. What else can you say. They do what they’re supposed to do, hold the brake disc on. I got them to add some color to the bike. They are supposed to be lighter…maybe a few grams. But they look cool!

Great replacement part for Zipp Wheels
This is a great replacement for the Zipp centerlock ring which requires a notch bottom bracket tool for removal. The Zipp ring is thin and it can be difficult to keep the tool engaged to remove the lock ring. This uses a cassette lock ring tool for removal which is much easier to engage for something tightened to 40nm. It does have a ticker profile so make sure it works on your bike. Also the colors are awesome.

Incorrect product photo!
The raw silver are actually silver, NOT purple like the photo depicts. Will likely be returning.

They give a nice pop of color and fit well.
This does exactly what it is intended to do, using the same tools you would use for your Shimano-branded lockrings. I've used it to hold rotors from both Shimano and SRAM, and it's worked perfectly. It's the exact size needed, so it fits without any interference. I have no problem with the price, and I've bought two. I use these to add a pop of color to both my gravel and road bikes, and they've proven durable.

Works as expected
Works as expected. Feels solid and durable. A little pricey. Would have preferred less contrasting text.

ホイールへのアクセントに
前に使っていたシャマルカーボンではホイール付属のロックリングを使用しており、ホイールの買い替えに伴い必要に迫られて購入しました。 ロードバイクが青っぽい色なので青のロックリングに。 フレームがエメラルドブルーっぽいのでやや違う色味なものの青系統が増えていい感じ。 ロックリングに限って言えば限りなく自己満足に近いパーツですが自分が満足できてるのでヨシとしてます。
